A silly rat walks into a movie theater, goes to the box office, and buys a ticket.
After a few minutes, he comes back and buys another one.
The scene repeats itself 5 or 6 times until the ticket collector, intrigued, says
“Excuse me, but why do you keep buying tickets?”
And she
“Um, there’s a gentleman at the entrance who every time I try to come in…
He’s snatching it from me”
